Prusa i3 MK Filament Guide ClipOn

prusaprinters

<p>The Prusa i3 kit comes without a filament guide - this is a problem when using stiffer filaments on small spools. The filament tend to unwind and get stuck when printing.</p><p>This filament guide is a two part solution, a base with a new <strong>ClipOn design</strong> to lock the guide to the Prusa frame and an interchangeable filament guide (loop).</p><p>The ClipOn Holder (base) it is securely locked to the aluminum frame, but still easy to re-position.<br>The loop has a friction fit into the holder that closes the filament loading slot and prevents the filament from escaping the loop when printing.</p><p>Selecting models:</p><ul><li>Select a ClipOn Holder with or without filament store hole.</li><li>Select a Loop size and if it should have filament slot.</li></ul><p>I often forget to put the filament through the loop when loading, the solution is the guide with filament slot.</p><p>If the holder has a loose fit, scaling it to 99% of original size should give a more tight fit.</p><p>Let me know in the comments if you have ideas or changes to the design.</p><p><strong>See also:</strong><br><a href="https://www.prusaprinters.org/prints/8773-prusa-i3-mk-filament-guide-dust-clearner-for-clipo">Prusa i3 MK Filament Guide Dust Clearner for ClipOn base</a> to use with the same holder.</p><p><i><strong>&gt;&gt; If you like it, please leave a like, a make or a rating… :) Thank You!</strong></i><br>&nbsp;</p><h3>Print instructions</h3><p>Print with PLA, ABS, PET-G or similar.</p><p>2 perimeters, 3 top and 2 bottom layers 30% infill.</p><p>Gcode file is for printing one holder and large loop in Devil Design PETG (MK2/S, MK2.5/S, MK3/S, MK3S+).</p><p><strong>Post printing:</strong><br>The loop should fit into the base, but you may need to smooth the loop guide surface with a knife or sand paper to get an easy friction fit into the base.</p>
